Hope this helps! God bless.
X/3 - 3/4 = 5/2
x/3 = 3.25
x= 9.75 Or 9 3/4
Answer:
1/8 cm = 0.125 cm = 1.25 mm
6 * (1.25 mm)^2 = 9.375 mm^2
Y=7+2x......(1)
put this value in 4y+x=1
4(7+2x)+x=1
28+14x+x=1
15x=-27
x=-27/15.....(2)
put this value in eqn (1)
y=7+2(-27/5)
y=7-54/5
y=-3.8
I really hope this helps :D:D:D!!!!
